Hi Mikevein,Welcome to our forum. ;DIf the negative 5.6V supply doesn't work then Q1 will turn on and cause U2 to get hot. Also the current regulator U3 won't work. Check that you have -5.6V across D7.

Make sure that you have the substitute transistors wired correctly. If they have the collector and emitter mixed up then their current gain will be low and cause U2 to get hot.

The current regulator works by reducing the output voltage by pulling the voltage down with D9. Make sure that D9 is not open.

when i was testing my power supply, i found out that i couldn’t limit current. I test another motor and at that moment i saw that current is about 7 amps !!!!!When i disconnected the motor, voltage became 35V and i can’t change it with P1

Now neither P1 nor P2 work. but short circuit protection was working, but after doing few short circuit, LED didn't turned on pls help!
